An electronic circuit for generating a delayed radio signal for use in a radio communication device configured to provide a transmit baseband signal in a baseband, to up-convert the transmit baseband signal into a transmit radio signal in a radio band, to transmit the transmit radio signal in the radio band, and to simultaneously receive a receive radio signal in the same radio band, is provided. The electronic circuit may include a delay circuit configured to delay a copy of the transmit baseband signal by an amount of time to generate a delayed baseband signal, an up-converting circuit configured to shift the frequency spectrum of the delayed baseband signal to the radio band to generate a delayed radio signal, and an output circuit configured to output the delayed radio signal for a cancellation circuit to cancel the delayed radio signal from the receive radio signal.
